Coverage Types for Engineers
These are the key insurance policies most relevant to your business type — ranked by importance.
Professional Liability (E&O)
RequiredCovers claims arising from errors or omissions in your engineering designs, calculations, specifications, or reports. A structural failure, mechanical system that doesn't meet code, or environmental report with material errors can all trigger E&O claims. Written on claims-made basis.
General Liability
RequiredCovers bodily injury and property damage during site visits, inspections, and at your office. Required by most project owners, GCs, and client contracts. Covers physical incidents separate from your professional services.
Workers Compensation
RequiredRequired in most states with employees. Engineers who conduct field inspections, site observations, and testing work face real injury exposure from construction site hazards, traffic, and equipment.
Cyber Liability
RecommendedCovers ransomware on CAD/BIM files, FEA models, and project data. A ransomware attack on active structural or mechanical engineering files can halt construction and trigger client delay claims.

What You Need to Know
- →Engineering E&O is claims-made — maintain continuous coverage from project start and purchase tail coverage when retiring or switching carriers. Latent design failures can surface years post-construction.
- →Your PE stamp creates professional accountability — once you stamp and seal drawings or reports, you accept personal professional responsibility. E&O insures that accountability.
- →NSPE and discipline-specific societies provide guidance on minimum E&O limits — check your state PE board requirements as a floor, then adjust to match your project exposure.
- →Owner and GC contracts typically require $1M–$2M E&O. Infrastructure, government, and large commercial projects may require $5M+ through a primary policy plus umbrella.
- →Field inspection work creates bodily injury risk — even desk engineers who visit sites occasionally should ensure WC is in place if they have staff and GL covers their personal site visit risks.
What Does It Cost?
Solo consulting engineer (PE): $175–$300/month for E&O + GL. Multi-discipline engineering firm: $400–$900/month adding WC, cyber, and higher E&O limits.
